Area 27 (Nevada National Security Site)
Area 27 is a division of the Nevada National Security Site. It occupies approximately 49 square miles (130 km2) in the south-central portion of the NNSS. A portion of Area 27 was originally known as Area 410.
Area 27 was used for weapons assembly and staging.
The Super Kukla Reactor Facility was built in Area 27; it's now entombed in place.
Joint Actinide Shock Physics Experimental Research
Area 27 is home to the Joint Actinide Shock Physics Experimental Research (JASPER) Facility.
JASPER uses a two-stage high-energy shock gun to achieve shock pressures, temperatures, and strain rates similar to those attained in a nuclear weapon. It is specifically designed to conduct research using plutonium and surrogate materials as targets. Data from these experiments is used to determine material equations of state and to validate computer models of material response for weapons applications. JASPER experiments support the Stockpile Stewardship Program and complement subcritical experiments conducted in Area 1.
The facility is located in a decommissioned weapons assembly complex and was established in 1999. By April 2003, qualification testing using non-nuclear materials was complete. By May 2007, a series of tests comparing new plutonium weapons pits with old ones had confirmed that the plutonium cores in US weapons stockpiles were less subject to deleterious aging effects than previously anticipated.
